Agitation in children and adolescents: Diagnostic and treatment considerations

In a retrospective case series of 30 pedi­atric patients with autism spectrum disorder who were given oxcarbazepine, Douglas et al³⁵ found that 47% of participants experienced significant improvement in irritability/agitation. However, 23% of patients reported significant adverse effects leading to discontinuation. Insufficient evidence exists for the safety and efficacy of oxcarbazepine in this population.³⁵

Benzodiazepines. The use of benzodiazepines in pediatric patients has been associated with paradoxical disinhibition reactions, particularly in children with autism and other developmental or cognitive disabilities or delays.²¹ There is a lack of data on the safety and efficacy of long-term use of benzodiazepines in children, especially in light of these patients’ developing brains, the risk of cognitive impairment, and the potential for dependence with long-term use. Despite this, some studies show that the use of benzodiazepines is fairly common among pediatric patients who present to the ED with agitation.¹⁴ In a recent retrospective study, Kendrick et al¹⁴ found that among pediatric patients with agitation who were brought to the ED, benzodiazepines were the most commonly prescribed medications.

Other medications. Clonidine and guanfacine have been used off-label to treat agitation in children and adolescents, particularly among those with ADHD or autism. Some small pediatric trials have also shown their benefit in decreasing symptoms of aggression, impulsivity, and hyper-arousal in PTSD.³⁶ In addition to adverse effects that include but are not limited to lowered blood pressure, bradycardia, and risk of atrioventricular block, clinicians need to be vigilant for potentially serious rebound hypertension that may occur if doses of these medications are missed; this risk is greater with clonidine.

Diphenhydramine, in both oral and IM forms, has been used to treat agitation in children,³² but has also been associated with a paradoxical disinhibition reaction in pediatric patients²¹ and therefore should be used only sparingly and with caution. Diphenhydramine has anticholinergic properties, and may worsen delirium.¹⁵ Stimulant medications can help aggressive behavior in children and adolescents with ADHD.³⁷

Bottom Line

Agitation among children and adolescents has many possible causes. A combination of a comprehensive assessment and evidence-based, judicious treatment interventions can help prevent and manage agitation in this vulnerable population.
